Also, the combination of harmonics and capacitors in a system could lead to a more severe power quality condition called harmonic resonance, which has the potential for extensive damage.
Capacitors are typically installed in the electrical power system – from commercial and industrial to distribution and transmission systems – as power factor correction devices. However, even though it is a basic component of a harmonic filter (aside from the reactor), it is not free from the damaging effects of harmonics.
Also, the combination of harmonics and capacitors in a system could lead to a more severe power quality condition called harmonic resonance, which has the potential for extensive damage. Consequently, these negative effects will shorten capacitor life.
Capacitors are important components within a power system: they are indispensable for voltage control, power-factor correction, and the design of filters. Their deployment may cause problems associated with capacitor switching and series resonance. Too large voltage, current, and reactive power harmonics induce capacitor failures.
In the presence of harmonics, the total power factor is defined as total power factor = TPF = cos0 = Ptotal Stotal (5-6) where Ptotal and Stota1 are defined in Eq. 5-4. Since capacitors only provide reactive power at the funda- mental frequency, they cannot correct the power factor in the presence of harmonics.
The working of the capacitor banks under a harmonic-rich environment may be adversely affected. The resonance between the inductance of the transformer and the capacitance of the capacitor banks may happen at specific harmonic frequencies. The capacitor does not generate harmonics.
